Kuroka

Kuroka (also known as Kuroka Toujou) is a character from High School DxD. She is a Nekoshou (a rare, powerful variant of the cat yokai Nekomata) and the older sister of Koneko Toujou.

She has a striking appearance: a voluptuous figure, long black hair with split bangs, and hazel-gold eyes featuring cat-like pupils. She typically wears a revealing black kimono-style outfit.

Originally a reincarnated Devil serving under a master from the Naberius clan, she killed her master to protect her younger sister Koneko from danger, which branded her as an SS-Class Stray Devil and one of the Underworld's most wanted criminals.

Kuroka is highly skilled in Senjutsu (using life force/Ki), Youjutsu (yokai magic), and various forms of magic, making her a formidable fighter on par with top-tier Devils.

Her personality is playful, teasing, flirtatious, and somewhat vulgar—she loves to tease others (especially using her sensuality)—but she deeply cares for her sister, though she struggles to show affection directly and often hides her kinder side behind mischief.

She later becomes associated with Vali's team and eventually finds a place more aligned with peace and her loved ones.
